wrox BAISER.

Application filed February 10, 1922. `Serial No. 535,627.

T 0 all whom, t may concern.'

Be it known that I, Funninuoi lV. Sri-iNe- Lnn, a citizen of the United States, residing at Oak Park, in the county of Cook,

Vin the State of Illinois, have invented a new and useful Improvement in Nick Baisers, of which the following is a specification.

The invention especially relates to wick raisers for lamps of the blue-flame mantle type, in which annular wicks are employed, although it may be advantageously employed in lamps wherein a luminous flame is directly produced by the combustion of oilvapor at the tip of the wicks.

Objects of the invention are to cause the wick to be uniformly raised and lowered at all partsV of its circumference; to prevent distortion of any portion ofthe wick which is disposed above the wick raiser, and to ensure the maintenance of a heating flame which will uniformly heat a mantle to an even degree of incandescence.

The invention consists, in general, of a wick band mounted in a novel manner between the inner and the outer wick tube of a burner, whereby the union and separation of the wick band and its mounting may be readily accomplished and the wick maybe adjusted in the burner without variations in uniformity of the exposed vaporizing area thereof.

In the drawingH Figure 1 is a view of aburncr in elevation, parts being broken away to sho-w the internal construction; n

Figure 2 is a view in elevation of the wick band and an associated wick; l

Figure 3 is a view in elevation of the wick-raising sleeve and the wiclm'aising rack; 4

Figure 4 is a vertical sectional view of the wick band and the wick raiser as as-` sembled in a burner, and

Figure 5 is a horizontal sectional view taken on the line 5-5 of Figure 1.

The burner is cfa known type, and it comprises a frame or basketl, screw-threaded at 2 for engagement with a reservoir, and carrying within its flange 3 an outer wicktube section l which, in turn, supports the upper sections 5, 6 of the outer wick tube, a flange 7 being mounted on said section 6.

A flanged collar 8 strengthens the joint between the basket 1 and the wick-tube sec-` tion 4. l

The inner wick tube 9 is heldin fixed relationto the outer wick tube by varies 10, 10 spanning the space between said wick tubes, the wick 11 being bifurcated at its band15 which is, preferably, permanently secured to the wick 11 by prongs 11, the object of said prongs being to preserve a true relationship between theband and the wick, and thereby maintain the accurate adjustment of the wick which is made by the factory experts.k The band 15, in addition to .being provided with openings 16 which limit the downward conduction of heat, has outward and oppositely-disposed points or protuberances 17 constituting pivots and formed by displacing or indenting'the metal of the wick yband from the inside. The wick-raising devices also include a sleeve 18 to which is attached a rack 19 actuated in the usual way by a pinion shown by dotted lines in Figure 1.

The sleeve 18 is provided with upwardlytapering resilient arms 20, 2O which may be corrugated, as at 21, to stiffen them, and these arms have holes 22 in their upper ends,

which are adapted to receive the points or' protuberances 17. The band 15, as thus mounted, is free to oscillate in its bearings in the arms 2O of the wickraiser, and to maintain its true relation to the inner and the' outer wick tube of the burner regard-- less of the degree to which it is adjusted by the wickiaisiiig mechanism.e The cranip ing of the wick and its supporting sleeve in the space between the wick'tubes which has heretofore been occasioned by the rigidity of the connection between the said sleeve and the wick-raising devices, is thus avoided. As a further result of this manner v of mounting the wick band, the thrust of the wick raiser is rendered uniform around the entire circumference of the wick, so that the wick may be raised without liability of distortion due to excessive pressure at one side thereof. n

The protuberances 17 are approximately seini-spherical and the arms 20, are resilient with the upper ends bent slightly youtward to enable them to be forced apart and to automatically engage with said protuberances when in coincidence therewith, to facilitate the union of the wick band and its mounting. Vhen the upper section 5 of the outer tube is in position inthe burner the upper outwardly-bent extremities of the wick-mounting arms 2O may slightly rub the inner wall of the section 5, to thereby prevent disengagement of the wick band and its mounting.

The vanes 10 operate as stops to limit the movements of the wick, the band l5 contacting with the upper edges of said vanes when the wickdescends, andthe sleeve 18 contacting with the lower edges of said vanes when the wick ascends. Y

Hav-ing thus described my invention, what I claim is:

l. A wick raiser comprising awick-carrying band, a band-raising means, and a shallow ball and socket joint connecting said wick-carrying band and said band-raising means.

2. A wick raiser comprising a wick band, and a wick-raising mechanism connected with said band by-diametrically disposed and shallow ball and socket joints.

v 3. A wick raiser comp-rising a wick band having male members of a shallow ball and socket joint, and a wick-raising mechanism having female members engaging said male members.

pivots, and a sleeve having resilient, perforated arms engaging said pivots.

5. A lamp provided with a wick raiser having detachable ball and socket joints constituting pivotal parts, oneo'f which'is resilient and operates to maintain said pivotal parts in engagement, theunion of said parts being ensured by an encircling element of the lamp. n j

G.l The combination of a lamp having inner and outer wick tubes, a vane connectin g said wick tubes, and a. wick-raising means comprising separable parts respectively disposed above and below said vane.

7. A wick raiser including a sleeve having oppositely disposed arms extending upward therefrom, an annular wick extending upward through said sleeve, andv means for pivoting the upper ends of said arms to the wick whereby said wick may be raised or lowered without tilting.

. 8. A wick raiser including a sleeve having oppositely disposed arms extending upward r" therefrom, a rack attached to said sleeve, an annular wick extending upward through said sleeve, and means for pivoting tl-'ieupper ends of said arms to the wick whereby said wick may be raised or lowered Without tilting.

In testimony whereof, I aliix my signature.
